head to head
Neither is meaningfully harder - they pose close to the same test. The widest gap is reads, and it is a single point.

Variance · Systems & Chaos
A narrative card game where balancing four meters under random event draws is more luck-management than strategy.

Variance · Systems & Chaos
A dice-and-cards board game testing quest routing against heavy draw luck.
Reigns leans Variance (Systems & Chaos); The Witcher: Adventure Game leans Variance (Systems & Chaos).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Reigns
Swiping cards left or right has no skill dimension
The Witcher: Adventure Game
Digital board game - clicks only
The Witcher: Adventure Game leans a little harder on reads, though the gap is small.
Reigns
Card characters react to prior choices in semi-scripted ways
The Witcher: Adventure Game
Human rivals race and block, but interaction is shallow
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Reigns
Event card ordering and hidden outcome RNG dominate play
The Witcher: Adventure Game
Dice combat and event card draws dominate single quests
The Witcher: Adventure Game leans a little harder on optimization, though the gap is small.
Reigns
Learning which choice chains balance the four meters is mappable
The Witcher: Adventure Game
Quest routing and risk-odds management reward planning
A matching score does not mean a matching test. Two games can both sit at 10 on execution and demand completely different things of you - which is why the reasoning above matters more than the number beside it.
